Hello my name is Josh and I just purchased a 450exc. I plan to supermoto it out and was wondering the best wheel size combo to use on that bike. Also would you recommend putting on better front brakes or will the stock ones work? Not planning to race it just tear up the streets of long beach. Also anyone know of some cool graphics? Thank you for your time

3,5*17 front with a 120/70 tyre
4,25 (with a 150/60 tyre) or 5 (with a 160/60 tyre)*17 rear, choice is yours. I ran a 5 so I could use 160/60 tyres which is a more common size, meaning more tyres to choose from. a 4,25 rim with a 150 tyre will give you more clearance at back. if you want more info on wheel sizing, wheel fitment and tyre selection you might want to use the search, there's numerous topics about these items with a lot of usefull info.

oversized rotor with relocater bracket for the stock caliper
14-45 gearing

that should get you started.
